The rapid increase in population, fast urbanization and change, high demand for public transport in Khartoum State necessitates development of a proper transportation plan for the state, to enable predicting the impacts that various policies and programs will have on travel. Travel demand forecasting is an essential part of the transportation planning process and trip production is the first step in the concept of four steps travel demand model. In this paper a model for trip production in Khartoum State is proposed. The trip generation model is based on data collected by the Ministry of Infrastructures and Transportation and a consultant in the period 2008-2011. The exclusion of incomplete data and outliers and the consideration of the car ownership in the development of the model, has resulted in a more realistic estimate of the number of trips produced than those predicted by the currently adopted model of Khartoum State. The results of this study predict the number of daily trips in the year 2035 at 9.56 million person-trips, creating a demand of 6.69 million person-trip/days to be covered by public transport. This will necessitate huge investments in mass transit systems to accommodate the uprising demand.
The purpose of this study was to investigate the effect of instructional games on immediate and delayed achievement in math's of 3rd grade students in Jerusalem Suburbs schools. The population of this study consists of 3rd grade students (N=1630) in the second semester of the academic year 2004/2005. The sample comprises two sections of 3rd grade (n=68) in Izareia Basic School، The two sections are divided into two groups; one as an experimental group which works with instructional games، and the second as control group that learns traditionally. An achievement exam was used to measure the immediate and delayed achievement with reliability (0.88). The results of the study have shown the following: (1). There were no statistically significant differences at (α=0.05) in the immediate achievement in math's of 3rd grade students due to the method of teaching or gender or the interaction between them. (2) There were statistically significant differences at )α=0.05) in the delayed achievement in math's of the 3rd grade students due to the method of teaching for the benefit of experimental group and in gender for the benefit of females. There were also no significant differences due to the interaction between method of teaching and gender. هدفت هذه الدراسة إلى التعرف على أثر استخدام الألعاب التعليمية في التحصيل الفوري والمؤجل في الرياضيات، لدى طلبة الصف الثالث الأساسي في مدارس ضواحي القدس؛ تكون مجتمع الدراسة من جميع طلبة الصف الثالث الأساسي في المدارس التابعة لتربية ضواحي القدس المنتظمين في الفصل الثاني من العام الدراسي 2004/ 2005م، والبالغ عددهم (1630) طالباً وطالبةً، وتكونت عينة الدراسة من (68) طالباً وطالبة، تم اختيارهم بصورة قصديه من مدرسة العيزرية الأساسية المختلطة، قسمت العينة إلى مجموعتين: مجموعة تجريبية درست باستخدام الألعاب التعليمية، ومجموعة ضابطة درست بالطريقة التقليدية، ولأغراض الدراسة قام الباحثان بإعداد اختبار تحصيلي لقياس التحصيل الفوري والمؤجل، وقد بلغ معامل ثبات الاختبار (0.88). وأظهرت نتائج الدراسة عدم وجود فروق ذات دلالة إحصائية (α=0.05) في التحصيل الفوري تعزى لطريقة التدريس، أو الجنس، أو التفاعل بينهما، وأظهرت أيضا وجود فروق ذات دلالة إحصائية (α=0.05) في التحصيل المؤجل تعزى لطريقة التدريس ولصالح المجموعة التجريبية، ومتغير الجنس لصالح الإناث، ولم تظهر وجود فروق ذات دلالة إحصائية للتفاعل بين طريقة التدريس والجنس.
